Some models including a defense graph model, attack-defense taxonomy and cost quantitative model, and Attack-Defense Game (ADG) model. We regard the interactions between an attacker and the defender as a two-player, non-cooperative, zero-sum, finite strategic game and formulate the ADG model for the game. An algorithm for optimal strengthening strategy selection based on those models is proposed. Optimal strengthening strategies with minimizing costs are used to defend the attack and strengthening the network in advance. And finally, we perform empirical experiments to verify the effectiveness of the model experiment results indicate that our models and methods are effective and efficient.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129264180","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents a new side-match vector quantization method for image coding using a neural network-based variance predictor. In this method, the master codebook used for generating the state codebooks in side-match vector quantization is sorted according to the variances of the codewords. Unlike the regular side-match vector quantization which side-matches all of the codewords in the master codebook to select codewords to construct the state codebooks, the proposed method side-matches subsets of the codewords in the master codebook, selected based on the variance of the current vector being encoded. The variance of the current vector is predicted by a feed-forward three-layered neural network. Experimental results demonstrate that in terms of PSNR (Peak Signal-to-Noise Ratio) of the reconstructed images, the proposed method significantly outperforms the regular side-match vector quantizer, especially at lower coding bit-rates.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126907218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Optimum Power Allocation for Distributed Antenna Systems with Large-scale Fading-only Feedback 大规模纯衰落反馈分布式天线系统的最优功率分配

In the conventional power allocation schemes for DAS, channel state information (CSI) for feedback includes the fast small-scale fading. This causes two practical problems. First, tracking fast fading requires considerable extra bandwidth and processing, which becomes even larger as the number of the distributed antennas increases. Secondly, there is non-negligible power control latency due to the high Doppler of small-scale fading and the feedback loop delay. In this paper, we consider a DAS system which determines the transmission power at each distributed base stations (antennas) only based on the slowly varying large-scale fading excluding the fast small-scale fading and we derive the optimum power allocation (PA) rule for minimum BER under total power constraint. In case of even small variation in fast fading during feedback loop delay, the conventional optimum PA scheme, which includes fast small-scale fading in CSI feedback, degrades significantly and the proposed scheme achieves much lower bit error rates. Even in the case with no latency, the proposed scheme loses only about 1dB SNR compared to the optimum scheme, which includes fast fading feedback. Finally, though the proposed power allocation formula is derived assuming Rayleigh fading, we show that it can be employed to Ricean fading channels with a small line-of-sight (LOS) component with a negligible degradation.","PeriodicalId":347761,"journal":{"name":"2009 Sixth International Conference on Information Technology: New Generations","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126458786","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The issue of confidentiality is that the plain texts of events should be kept private from the infrastructure to counter  against eavesdropping and that the infrastructure must remain able to make correct routing decisions efficiently. This paper presents a solution that allows confidentiality in a CBPS infrastructure without decreasing its performances such as efficiency, expressivity and scalability.

The concept holds many promises including cheaper power to the consumer, a more flexible and responsive power production and the support of a more environment-friendly development. In order to realize a software solution supporting the Generic Virtual Power Plant, an array of different software design principles, patterns and architectures must be applied. Especially Service Oriented Architecture (SOA) can aid in implementing the Generic Virtual Power Plant.
